EcoFlow EF BD-5.1-S1 Battery Module (5 kWh)

EcoFlow PowerOcean DC Fit is a unique solution that enables integration of an energy storage system with an existing photovoltaic installation. It makes achieving energy self-sufficiency easy and cost-effective by allowing batteries with capacities up to 15 kWh to be connected without replacing the existing inverter or AC wiring, which significantly shortens installation time and reduces investment costs. The system does not require a permit for grid connection, saving waiting time.

Key features of EcoFlow PowerOcean DC Fit:

  • No need to install an additional storage inverter.
  • Allows connecting batteries up to 15 kWh without replacing the existing PV inverter.
  • No need to replace AC wiring, which shortens installation time.
  • No grid-connection permit required, saving time.
  • Flexible battery configurations from 5.1 kWh to 15.3 kWh.
  • Supports floor-standing or wall-mounted installation.

Who is this a good choice for?

EcoFlow PowerOcean DC Fit is an ideal solution for owners of existing photovoltaic systems who want to increase their energy self-sufficiency and start storing excess solar energy. The system is suitable for both residential and commercial use, and its simple installation and lower upfront costs compared with traditional solutions make it an attractive option for a wide range of users looking to optimize their energy use.
